Localization: every component that contains any label needs to be properly localized, that means, default text needs to be replaced with [[localiztion-string]] and Languages.Localize(component) needs to be called for each of them. In addition all new components that were introduced in huggle 3 needs to be inserted to localization files and synced on wiki. Configuration: CoreIO.cs: SaveLocalConfig() LoadLocalConfig() needs to contain all variables in Configuration that needs to be stored in local config file. Documentation: Every file now contains documentation in header + inline documentation as well. Insert it everywhere if it's missing. Keep the documentation base updated on mediawiki.org.
